YAG laser capsulotomy is a procedure used to treat posterior capsule opacification (PCO), a common complication that can occur after cataract surgery. PCO occurs when the posterior capsule of the lens becomes cloudy, causing vision to become blurry again after cataract removal.

In this procedure, a YAG laser is used to create an opening in the clouded capsule, allowing light to pass through and restoring clear vision. The procedure is quick, minimally invasive, and usually performed on an outpatient basis.

YAG laser capsulotomy is highly effective in treating PCO, with a high success rate in restoring vision and improving the quality of life for cataract surgery patients.
